I collected this rock during the summer of 2004 in the Pindos fold and thrust belt of the Peloponessos near the village of Ano Karyes. I like the fact that the fringe shoulder of the main joint face is so obvious, and thus the joint morphology is so complete. Moreover, the color reminds me of fudge.
